Ford claims both its C-Max Hybrid people-mover and its sleek Fusion Hybrid sedan get 47 MPG city and 47 MPG highway, earning them (of course) an EPA combined score of 47 mpg. However, Consumer Reports saw it differently:

“In our tests, the Fusion Hybrid delivered 39 mpg overall and 35 and 41 in city and highway conditions, respectively. For the C-Max Hybrid, we got 37 mpg overall, with 35 and 38 for city and highway. These two vehicles have the largest discrepancy between our overall-mpg results and the estimates published by the EPA that we’ve seen among any current models.”

Are you saying, “So what?” After all, there’s a disclaimer on the Munroney sticker that says “Your mileage may vary,” right? Consumer Reports claimed its overall MPG results are usually “pretty close” to EPA combined estimates. Previously, the largest discrepancy between that EPA combined fuel economy number and the Consumer Reports tested fuel economy was found in the Toyota Prius C, which returned 7 MPG less than the EPA combined score when tested.
